A strange little side quest
A quick detour while Sector waits for your next move: Doom changed game design and distribution in 1993 by separating its engine from content and spreading widely through shareware. Another piece of context lands nicely beside it: Nintendo's Donkey Kong arrived in 1981 and introduced the character first known as Jumpman, who later became Mario. Grombi files that under: small game, surprisingly large backstory.
